  • Publication number: 20090145449
    Abstract: A method of making segmented filters including moving substantially identical segments of one type at uniform rate to a transferring element, which places each segment separately on an exit path. Setting of the filter segments in a repeating group on the exit path is accomplished by delay in collecting segments by a transferring element in each module of the apparatus. Uniform positioning is effected using the transferring element which includes uniformly spaced drivers, and non-uniform positioning is effected using the transferring element with non-uniformly spaced drivers. The apparatus includes a guiding element positioned adjacent to a cutting drum and has a wall closing a channel for a set of segments drawn out of a flute on the drum. The filter set is led through the channel with the aid of a dog of a chain and is advanced by a worm surface of a pushing together drum.

  • Patent number: 7395641
    Abstract: A method relates to a production line where cigarettes are arranged in horizontal layers within approximately vertical channel (3) of packing machine feeding system, the width of which is slightly bigger then the cigarette diameter. The cigarettes are moved gravitationally toward the bottom plate (6) tram which they are transferred to the packing machine, whereas faulty cigarettes are detected with sensors (9, 11) defining their defects, and the faulty cigarettes are rejected by a rejecting device (14).

  • Patent number: 7044286
    Abstract: A method and device is provided that separates non-parallel streams of displacing multi-layered stacks of rod-like elements which fill a horizontal conveyor (wherein the elements are displaced by force) and a channel positioned at an angle (wherein the elements are displaced by gravity.) The inside dimensions of the cross sections of the conveyor and the channel allow an equal flow of the elements. To separate the streams, the elements are removed from the adjoining area of the conveyor and the channel, wherein the stack of the elements is a passive stream, to the area of the conveyor or the channel, wherein the stack is an active stream. The space that is taken up by the removed elements equals the space of one quarter of the radius of the cylinder, wherein the walls of the cylinder that are parallel to the axis of the cylinder, separate multi-layered non-parallel streams of the elements.

  • Publication number: 20040231961
    Abstract: In order to separate streams of multi-layered stacks of rodlike elements the rodlike elements are removed from the adjoining area of a horizontal conveyor (3) or a channel positioned at an angle (1), in which the stack of rodlike elements becomes a passive stream to the area of the channel (1) or the horizontal conveyor (3), in which the stack becomes an active stream, and the space taken up by the removed elements is equal to the volume of the appropriate sector of a cylinder of radius (r) corresponding to with (P) of the horizontal conveyor (3) and/or width (K) of the channel (1), whereas the walls of the cylinder which are parallel to the axis of the cylinder separate the non-parallel streams.

  • Patent number: 6422380
    Abstract: In the store at the inlet of the transport sector (11) is situated the first drive mechanism (21) of the conveyor (8) which is controlled by and connected to a fullness sensor (22) assembled in the input station (16) via a control unit, and at exit of the transport sector (11) is situated a second drive mechanism (23) of the conveyor (8) which is controlled by and connected to a fullness sensor (24) assembled in the output station (17) via a control unit, while the transport sector (11) is defined by two, active and passive, identical support guide mechanisms (10, 15) for the conveyor (8), consist of independent disc modules (6) rotary assembled on the axes (5, 14), moreover the return sector (9) consists of two, active and passive, identical support guide mechanisms (7, 13) of the conveyor (8), that consist also of independent disc modules (6) rotary assembled on the axes (4, 12), while the axis (5) of the active support guide mechanism (10) in the transport sector (11) is fixed to the axis (4) of the active
